LOADING APPAATUS.

SPECIFICA'llON forming part of Letters Patent No. 684,911, dated October22, 1901. Application tiled February 4, 1901. Serial No. 46 ,007. (No model.)

Ohio, have invented certain new and useful Improvements in Loading Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 1o which it appertains to make and use the same.

My invention is an improvement in loading apparatus; anditconsistsin the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate :5 one form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 zo represents a top plan View of a machine or apparatus embodying my invention. Fig. 2 is a side view of the same. Fig. 3 is a transverse vertical sectional view on line 3 3 of Fig. 1. Fig. 4E is a central longitudinal sec- 2 5 tional view. Fig. 5 is a detail view of a part of the shovel or scraper and sliding back plate.

The apparatus herein shown is designed particularly for removing coal or ore from low veins and loading it onto cars or trucks;

3o but it will be apparent that it may be conveniently used for other purposes.

In the apparatus shown in the drawings, the main frame consists of two side bars A A, connected by a rear frame-bar A'. The front ends of the side bars are connected bya drop-axle B,on which are mounted the main supportingwheels C C outside of the side bars A A, and the rear frame-bar will be provided with one or more caster-wheels C', one being shown lo- 4o cated centrally of the said rear bar. Upon the main frame is mounted a rectangular frame D, having its rear end pivotally connected to the main frame. In this instance the rear end of frame D is provided on opposite sides with trunnions d d, which engage bearings a a, carried upon the main frame-bars A A. The forward end of the pivoted frame D is provided with ropes, chains, or other flexible connections e e, preferably connected to 5o bracket-arms d' d', secured to frame D and projecting below the same. These connections e e extend upward over idle pulleys e e', mounted on brackets a' u', secured to the' Y jecting lugs g' g, engaging normally the upper sides of said rods F F to prevent the scoop The shaft E is provided,l

from dumping rearward. I prefer to provide the scoop G with removable pins g2 g2 or equivalent devices to engage the rods F F below the same to prevent the scoop from dumping forward unless it is desired to have it do so, when said pins willbe removed by hand.

On the tilting frame D is mounted a shaft I-I, provided with a sprocket-wheel h in line with each ofthe rods F, and each of said rods is provided with a sprocket-chain f, passing over one of said wheels h andhaving its ends secured to the rod F. The pinions h h are loosely mounted on the shaft H and are adapted to Ybe rigidly secured thereto by means of sliding clutch members h h', connected to the shaft by splines.

F represents a longitudinally-sliding bar mounted centrally in the pivoted frame D and provided at itsy forward end with an end plate G', which forms the dumping end wall 'of the scraper or shovel G and which is separate therefrom. In Yorder to allow for the dumping of the scoop or shovel, the bottom plate of the latter will be provided at its rear end with a transverse slit or aperture g3, through which the dumping end wall may pass when the scoop yis dumped, and the rear end wall of the scoop is provided with a recess g4 to accommodate thev rod F', as shown in Fig. 5. The rod F' is provided with a rack' f', which is engaged by a pinion h2, loosely mounted on the shaft H and adapted to be secured thereto by a sliding clutch member h3, splined on the shaft.

h6 represents a shifting bar having a longi- ICO tudinal movement transversely of the machine. h4 represents a yoke connected therewith and engaging the clutch member 71,3. The clutch members h 7b are also connected to the shifting bar 71.7, so that they will be thrown ont of operative position when the clutch member h3 is thrown in, and vice versa. In this instance a yoke 7a4 engages each of said clutch members 7M 7V, one of said yokes being rigidly secured to the shifting bar h6, while the other is pivoted between its ends at h" to a stationary part of the frame and has its end loosely pivoted to the shifting bar. This arrangement secures the required operation of the clutch members h h and ha. The shift-ing bar is provided with a hand-lever 71.7 for operating the same.

The operation of the apparatus is as follows: The machine being in the position shown in Fig. 2, with the frame D lowered, so as to bring the scoop close to the ground, the machine is run into the mine or to any other point where material is to be removed and is placed with the scoop in front of the material to be operated on. The shiftinglever hl is then moved so as -to clutch the sprocket-wheels h 7L to shaft H, and thereby unclutch the pinion h3. rlhe operators then turn the shaft ll by means of suitable handles h5 or other operating de- Vices, thereby moving the rods F F forward and forcing the scoop under a portion of the material, so as to fill the scoop. I prefer to provide means for holding the main frame against backward movement during this operation, and in this instance I have shown it provided at its rear end with a pair of pivoted drop-arms K K for engaging the ground to lock the frame and a pair of upwardly-extending'r pivoted arms K' K for engaging the roof of the mine, if the apparatus is being used in a tunnel or mine. These arms K K will be folded out of the way when not in use. The scoop or shovel being loaded, the shaft H will be turned in the opposite direction, so as to withdrawit and bring it back until it rests over and upon the drop-axle B, the upper face of which is provided with the roller or rollers ZJ to avoid friction. This brings the weight of the load upon the main wheels C C. The operators will now rotate shaft E by means of the handles c e4 and raise the front end of the frame D and the chute, thus preventing the load from spilling. The machine is now pushed out of the mine or tunnel and to the place where the load is to be discharged into a car, truck, chute, or dump-pile, as the case maybe. lVhen in properposition, the shaft H is again turned and the scoop is run out until it is in proper position over the car or truck or chute to be dumped. The scoop can be dumped in either of two ways. If it is desired to force out the load without changing the position of the scoop, the opera-tor shifts the lever h? so as to throw the clutches L 7L' out of and the clutch 71.3 into engagement with pinionh?. The shaft II is then rotated so as to push forward the rod F and 4the dumping end board or plate G, (see Fig. 5 and the lower position in Fig. 4,) thereby discharging the load from the scoop. It' it is desired to dump the scoop on its pivots, the end-board Gr is left in its rearmost position and the pins g2 are removed, when the scoop or shovel will turn on its pivots, as shown in the upper dotted position, Fig. 45, and discharge the load. The apparatus is then restored to its normal position and is ready to repeat the loading operation.

I do not desire to be limited to the exact details oi' construction herein shown and described, as slight variations may be made therefrom without departing from my invention.

NVhat I claim, and desire to secure by Letters Patent, is

l. The combination with the main frame, of longitudinally-movable guide-rods movably supported thereby, a scoop carried by said guide-rods, chains connected to said guide-rods, actuating chain-wheels engaging said chains to project and retract said scoop and guide-rods and operating devices for said chain, substantially as described.
